Popular Socialist Party of Cuba

The Popular Socialist Party (PSP), also known as the Communist Revolutionary Union, was a Marxist-Leninist communist political party in Cuba that existed from 1925 to 1961. The PSP was led by Julio Antonio Mella until his assassination in Mexico in 1929, and the party supported Liberal Party of Cuba leaders Gerardo Machado and Fulgencio Batista during the 1940s. The victory of the national syndicalist Partido Autentico in the 1944 elections led to the PSP declining, and the party held only a few seats in the House of Representatives during the late 1940s and early 1950s. In 1961, the party merged into the Communist Party of Cuba.
